Hi Michael -

Thanks very much.

Truly tho, I'm a total XSL newbie & am looking for a handout. :)

 How might I make an xsl function for this & how would I call it?
Anyone care to help?

tokenize($in, '\W')[position() = 1 to $n]

Thanks --
Matt

In XSLT 2.0, that's

tokenize($in, '\W')[position() = 1 to $n]

where $in is your input string and $n is the number of words.

It's a fair bit harder in XSLT 1.0 (most things are).
